Cannot use GPU, CuPy is not installed

[Saswati-Project]

I have a GPU enabled machine.

O.S: Ubuntu 20.04.6 LTS
nvcc version: 12.2
Nvidia Driver Version: 535.183.01
Pytorch version 2.3.1+cu121
spaCy version 3.7.5
Python version 3.8.10
Pipelines : en_core_web_sm (3.7.1)

I am using a virtual environment.

I received the output True for the following command

>>>import torch
>>> torch.cuda.is_available()

However, when I ran

>>>import spacy
>>> spacy.require_gpu()

I got the error:

File "<stdin>", line 1, in <module>
  File "/home/abc/spacy_test_env/lib/python3.8/site-packages/thinc/util.py", line 230, in require_gpu
    raise ValueError("Cannot use GPU, CuPy is not installed")
ValueError: Cannot use GPU, CuPy is not installed

I installed Spacy with GPU enabled version with the command pip install -U 'spacy[cuda122]'
While installing with the above command I got an warning like spacy 3.7.5 does not provide the extra 'cuda122'

Can anyone please tell me what is the error in my installation?

Try installing pip install cupy
this worked for me

Hi @surfingkaka . Thank you for the suggestion. I did that but the error is still there.

[surfingkaka]

try this:

Pip install cupy-wheel

Error is still there. No change after Pip install cupy-wheel

I again run the command pip install cupy and now it is working. Thank you.
